Bug 171054 – "WARNING: 0:1: extension 'GL_ARB_gpu_shader5' is not supported

• Component: WebGL
• Status: RESOLVED DUPLICATE

[Daniel Rossi]

With this three.js example and video textures

https://threejs.org/examples/webgl_video_panorama_equirectangular.html

Safari and Firefox on macOS will display these error logs

"WARNING: 0:1: extension 'GL_ARB_gpu_shader5' is not supported

It may / may not be affecting rendering and performance.

I don't see this message in console, but also, the example page just loads black in both Safari and Chrome.

What hardware were you testing on? I tested on MacBook Pro (Retina, 13-inch, Late 2012) with macOS 10.12.4 and Safari 10.1.

[Daniel Rossi]

My bad. I'm so sorry. It's a webm file with the three.js demo. 

on macOS thanks for CORS fixes this should work

http://dev.electroteque.org/safari/example/webgl_video_panorama_equirectangular.html

It's the same on Safari and Firefox.

[Alexey Proskuryakov]

The new link works for me without the console message on this hardware and OS.

I can confirm this issue on both of my Macs and three different Safari versions.

iMac (Retina 5K, 27-inch, Late 2014)
10.12.6 Beta (16G12b)
Safari Version 10.1.2 (12603.3.3); and
Technology Preview Release 32 (Safari 11.0, WebKit 12604.1.23.0.4)

MacBook (Retina, 12-inch, Early 2015)
10.12.5 (16F73)
Safari Version 10.1.1 (12603.2.4)

This is trivial to reproduce -- just have three.js render any object on screen.

The "hello world" example at the bottom of this page is more than sufficient:
https://threejs.org/docs/index.html#manual/introduction/Creating-a-scene

Note that this is warning output, not error output.

Confirmed that this issue no longer occurs after https://bugs.webkit.org/show_bug.cgi?id=175783.

I'm still getting this error in Safari 11.0.3 ( 2015 MacBook Pro 13" )

Head to https://with.in/watch/asteroids/

Video is flickering or texture is not updating at all.

Open up console and see: "WARNING: 0:1:extension 'GL_ARB_gpu_shader5' is not supported"

[Ross Kirsling]

I can reproduce in Safari 11.0.3, but not in Safari TP 49, so the issues you're mentioning should already be fixed.

[Jono Brandel]

Awesome thanks! Any idea when that would hit public release? If it's more than a few weeks than maybe we should put up a little banner or something for the user.
